[Prior art]
2. Description of the Related Art Conventionally, in a ground-mounted oil supply device provided at a gas station, an oil pump accommodated in a case is connected via a pipe from an underground tank and a suction pipe. However, when the oil pump is placed below the pump motor, the length of the suction pipe is shortened, the work space is reduced, and when the positions of the suction pipe and the underground tank are misaligned, connection adjustment work is not possible. It could be difficult. Therefore, for example, Japanese Examined Patent Publication No. 2-60600 discloses an improved oil supply in which an oil supply pump is arranged above the pump motor so that the suction pipe connected to the oil supply pump can be easily connected to the pipe from the underground tank. A device has been proposed.
